How snails reproduce

It is well known that most snails are hermaphrodites, which means that they have both a penis and a reproductive system feminine. However, there are other kinds of snail that are only male or female. Whatever its gender, a snail cannot fertilize itself, so it needs a partner to reproduce. But,how snails reproduce? Below oneHOWTO reveals in detail what for many is a mystery.

Mating times

Regarding the ideal time to reproduce, these invertebrate mollusks prefer spring and fall because the climate it tends to be more temperate, but also quite humid. With a life expectancy of 5 to 7 years, after exceeding 6 or 8 months of age, the snail is considered sexually mature.

Game of seduction

First, the courtship between two snails begins. This game of seduction is presented with the mollusks moving in circles around each other, feeling each other with their mouths, and this is how they intertwine their bodies. And it is that absurd as it may seem, snails also play games preliminaries during the mating process, which usually takes about 20 minutes. These animals need to be excited before copulating, and for that they resort to chalky dart of its morphology, located inside the genital orifice.

Copulation

During copulation, one of the snails inserts its dart into the other’s female reproductive system and both wait for it to lodge in the oval pouch of the vagina.

Reproduction in snails is extremely long, lasting between 10 and 12 hours. This is because after that time has elapsed is when the ovules are mature and ready to receive sperm with which to carry out fertilization.

During reproduction, which occurs at night, both snails are released DNA strands mutually in the form of calcium carbonate. Upon receiving them in the female reproductive system, they dissolve and release the sperm. After 10 or 12 hours, the eggs mature and accept the sperm, as mentioned, and this action causes both snails to be fertilized, forming eggs inside.

The eggs

After 15 or 20 days, the snails dig a hole underground with their head and foot where they deposit their fertilized eggs, turning it into a nest. Mollusks expel between 50 and 80 eggs of about 3 mm from their genital orifices over this hole. Other snail species They can lay around 200 eggs, like the Chinese snails, and even up to 700, like the African Achatina snails.

Birth

Finally, after 16 or 30 days the eggs get hatch and the young are born, which remain in the nest for 3 or 5 more days until they quit. To get outside, they devour the membrane that lines their egg, which provides proteins and mineral salts, as well as the earth that covers their nest. That’s when these snails they begin the cycle of life.
